Picmal is a Mac app for converting, compressing, and editing images, video, audio, and PDFs. Simple by default. Drop your files in and go. No setup, no need to know what a bitrate is.

It does a lot: batch up to 10,000 files at once, read RAW photos from most cameras, watermark photos and video, resize and recolor images, and compress to a target file size without ever making a file bigger. Beyond converting, it can merge audio into chaptered audiobooks, combine videos, burn in subtitles, split and organize PDFs, build PDFs from images, and generate app icons for macOS, Windows, and iOS. It plugs into Finder Quick Actions, Shortcuts, Raycast, and a full command-line tool, and can watch folders to process new files on its own. If you want more control, there's an advanced mode. The defaults are already sensible, so most people won't touch it.

It feels native because it is. Picmal lives wherever your other Mac apps live. Everything runs locally, so your files never leave your machine.
